API Keys

Warning: Google API Keys are not included with these packages as mentioned in both PPA Links. The process of creating them is quite involved and only recommended for developers!

Do not update chromium-browser from those PPAs if you haven't understood the process below!

NOTE: Some Chromium features, including Sync, require an API key,
which is not included with the packages below. To use these features,
please follow the 11 steps at
http://www.chromium.org/developers/how-tos/api-keys. Then, open
.profile located in your home folder (you will need to see hidden
files), and add the following three lines to the end of the file (on a
new line):

@RaduRădeanu Correct. Thanks for pointing me out of the amount of developers on that PPA.

@Radu Rădeanu That is just FUD. These PPAs are being built today and are currently in the build queue and should be finished tomorrow, as the tarballs were released just today. Not sure why that needs to be brought up. It is similar to PPAs like launchpad.net/~a-v-shkop/+archive/chromium that were maintained by one person and it was never an issue.

At this point, it appears that the builds linked off of the Chromium Browser pages on Launchpad have become inactive and out of date. The last dev, beta, and daily successful builds from this particular project were made about 65 weeks ago(over a year).

As far as the ppa:a-v-shkop/chromium PPA goes, it looks like the builds had some issues back in April(?) as a result of Google changing the ToS on the use of their Google API keys that have yet to be resolved. I am waiting to hear back from the maintainer on their status.

New Chromium PPAs available

Currently, there are two new Chromium PPAs available for dev and beta. I spoke with the maintainter, yesterday on the status of his PPAs, and it appears that he kicked off some new builds within the last couple of hours.

Here is the dev build PPA available on Launchpad. - currently at version 29.0.1547.15

Here is the beta build PPA available on Launchpad. - currently at version 28.0.1500.89 (build is still pending as I write this)

Additionally, there are two Debian/Ubuntu channels(dev and beta ) provided be Google: that provide deb packages for installation. See The Chromium Dev-channel projects page for additional information. Note that these deb files are branded as Chrome and not chromium, but they do appear to following the versioning as laid out by the Development Release Calender

The most current build is available directly from the trunk runs a number of version ahead of that as laid out by the release calender. Note that this needs to be installed manually (See @Radu's answer), and reportedly will require manual updating).

Launchpad chromium-dev PPA

There is a chromium dev build(>= version 29.0.1547.0 at this time) available as a PPA here.

Installation from the command line:

The latest dev PPA can be obtained by running the following commands from the terminal(Ctrl-Altt):

Canonical seems to have decided to get involved in providing more recent Chromium builds, from what I can tell. Previously, keeping Chromium current was up to the Community. You can read about it here:Fwd: Fwd: Chromium Updates andNew updates for Chromium.

Edit: my personal prejudice for a stable experience, as far as such is possible, is to stay with Chrome stable and not to experiment with Chromium builds.
